Netfilter is the FOSS software community-driven project, launched in 1998, that provides firewalling tools for the GNU/Linux operating system. The Netfilter Workshop (NFWS) is the main event organized for and by the Netfilter community. During the workshop days, Linux kernel networking and Netfilter developers meet and discuss the status of the on-going Netfilter-related developments and the plans for the near future.

Following the lastest successful NFWS in Berlin, Germany. We are glad to announce that the next event in these series will take place in Malaga, Spain, in dates July 9th-12th 2019. There is an international airport (AGP) with direct connections from main European hubs.

This event will be hosted by School of Computer Science Engineering at the Teatinos Campus of the University of Malaga.

Call for participation

Attendance requires an invitation. Linux networking developers with contributions to any of the Netfilter subsystems and users with interesting usecases and open problems are also welcome. We have traditionally left room for other projects that rely on Netfilter infrastructure such as the Linux Virtual Server project. You can send us proposal in a very lightweight format: title and quick abstract (not more than 500 words!) as well as estimated time to present.

Please, send us your proposal to coreteam@netfilter.org before 30th May (strict deadline). We have a very limited number of invitations, don't procrastinate!


We are looking for sponsors, so please contact coreteam@netfilter.org and we'll send you our sponsorship policy.
